Hi, For the midiboxes inside wiring the preferably is using the ribbon cable which are ( from wikipedia ) : ..The wire is usually stranded copper wire, usually either 0.32, 0.20, or 0.13 mm2 (22, 24, or 26 AWG)... The 10 m ribbon cable single wire has the similar resistance ~ 1,19Ω. Regards, Janis

Hi, I do not know many things, sorry. I did some more reading for myself, too: especialy #4 There are the some parameters for Arp controling in the Parameter Chart of MIDIbox SID V2 . Thorsten can give the best advice for you, I think. Regards, Janis

Hi, It is not difficult to add in this code string DIN_ENTRY CS_MENU_BUTTON_Arp, 0, 0 ; enables/disables the arpeggiator of *all* oscillators the right SR# and Pin# instead of ,0,0 . The each button , encoder has own physical place in a shift register chain and it are need to be documented in the setup file. after your changes are saved the next step is: http://www.midibox.o...hain_quickstart Regards, Janis

Hi, Looks cool design! The setup_6581.asm and setup_8580.asm files have entries for Arp ON/OFF function already. Only you need to enter the right SR# and Pin# for your own setup and to make the new *.hex file. ;; new for MBSID V2 (additional ***optional*** buttons) ;; don't worry, you still have full access to all functions w/o these buttons! ;; note that you could also re-arrange the pin assignments if required (e.g. if you don't like a certain button function) DIN_ENTRY CS_MENU_BUTTON_M_Vol, 9, 5 ; matrix: button below M_Filter DIN_ENTRY CS_MENU_BUTTON_Play, 9, 6 ; direct access to play function DIN_ENTRY CS_MENU_BUTTON_SID_LR, 9, 7 ; direct access to L/R toggling DIN_ENTRY CS_MENU_BUTTON_M_Mode, 10, 0 ; direct access to meter on/off function DIN_ENTRY CS_MENU_BUTTON_Fil_ExtIn, 10, 1 ; direct access to Filter ExtIn Flag DIN_ENTRY CS_MENU_BUTTON_Sync, 10, 2 ; jumps to ENS->CLK menu DIN_ENTRY CS_MENU_BUTTON_Arp, 0, 0 ; enables/disables the arpeggiator of *all* oscillators DIN_ENTRY CS_MENU_BUTTON_Knob, 0, 0 ; changes to knob menu I did not find entry for the Arp ON/OFF led. I have an interest to add the Arp led for my design, too. Regards, Janis

You can bridge pins 4 and 5 inside your MB Sid

sorry... , #6

Hi, I remember the similar question from this topic: ,#6 Regards, Janis

Hi, In the all headers ( JP... ) the pin2 is connected to GND ( common ) rail. JP5 pin1 is + 5 volt out JP6 pin1 is for the led + pin ( anod ) JP4 pin1 is + 9 volt out JP3 pin1 is + 12 volt out Regards, Janis

Hi, In this case you need to read some more about Power supply option D. In this power supply schematic for the MB6582 then not more necessary -12volt supply rail : IC2 ( 7912 ) and the some another components connected with it. Regards, Janis

Hi, I have the additional linear voltage regulator with the LM7808 ( 8 volt ) ic to the MB6582 fan. Not used the heatsinks for the Sids. Regards, Janis

Hi, The SR's electrical parameters for the Dip16 and So16 cases are look very similar. Only a difference I found is in a Note1 at a page 8 from the attachment file. Regards, Janis 74HC595.pdf

Hi, I found this: http://export.farnell.com/stmicroelectronics/stp60nf06l/mosfet-n-logic-to-220/dp/9935657?whydiditmatch=rel_3&matchedProduct=PHP50N06LT&Ntt=PHP50N06LT Regards, Janis

Yes, its normal. A small code part from the setup_mb6582.asm file, last revision : ;;DOUT_ENTRY CS_MENU_MODE, 0, 16+1, 3 ; Sync LED **new** DOUT_ENTRY CS_MENU_MODE, 1, 16+1, 2 ; CC LED DOUT_ENTRY CS_MENU_MODE, 4, 16+1, 1 ; Edit LED DOUT_ENTRY TMP5, 6, 16+1, 0 ; Play LED **new** Why Sync led is not active by default? I do not know. Regards, Janis

Hi, In the data sheets pages ( for the both on pages 8 ) its possible to find the power supply current for the each type of SID, for the each voltage. Regards, Janis 6581.pdf 6582.pdf

Hi, May be some deeper Midi Troubleshooting section reading can help : http://ucapps.de/howto_debug_midi.html The merger board photos on the both sides can be helpful, too. The optocouplers are easily to replace from the one socket to another. You have the working Core with the working Pic controler. You can upload many application ,too. The mergers board Midi out and Midi In2 sockets are able to work with the Pic controler from the Core module, I think. Regards, Janis

The Supply circuit parts on the Core and on the Merger boards are very similar or identical, I think. In this case you have a possibility to compare how "looking components" B1, IC4, etc. on the one board and how - on the another board. Last time i rarely using the Mios studio. When you had connected the core module with the Mios studio is every time the Device ID number stay the same ( by default ID=0, I think)? Are you refreshing the Mios studio every time when you made a new connection ? Be patient. Regards, Janis

Its the same. I never saw this bord in live, but I think the J2 + 5v terminal is conected together with the JP4 +5v terminal already. is the diode bridge polarity right oriented ? Regards, Janis

Hi, the chips are better to hold in the antistatic covers (tubes) ! From my expierence. I bought SID chips from our forum members two times in a non workable condition. I think static electricity can easily to damage the famous SID cips ( if it were workable before ). Regards, Janis

Hi, Are you have this merger : http://ucapps.de/mid...rger_pic18f.pdf Regards, Janis

Have a fun ! later i saw the FC-10 connector inside is symmetrical constructed , sorry for a big trouble. for the Core module the better power supply solution is less than 12v : (7,5 to 10) v. Regards, Janis

Hi, For the MB Sid the right testtone application is here: http://www.ucapps.de...esttone_v3c.zip Good luck ! Janis

Hi, May be a stupid question. Are the both ribon cable conectors FC-10 are oriented in the same direction as a pin1 of the J10 is connected with a pin 1 of the J2, etc ? If you are looking from one end of the cable you can see the both connectors the first pin markers from the left side. regards, Janis

Capacitor value 223 is 22nF which is not right filter capacitor value for the 6581.Try the another pair of capacitors from the first MB Sid pcb. http://www.muzique.com/schem/caps.htm Regards, Janis

Hi Jason, Are you using right filter capacitors C1, C2 for the MOS6581 - 470pF ? On your Sid pcb photos I see different types( not capacitances ). Regards, Janis

Hi Moon, I had a very similar task. For me I found the better solution to use the "option B" with the all needed components for this option on the Base pcb. The power supply I made new like the C64 power supply with the 2 output voltages. The +5 VDC part I realised with the SD1084 chip ( LT1084 is the similar chip from the another manufacturer, applications can find on the net) in TO220 case . There are the 5 amp diode bridge and the 4700uF capacitor in my schematic input part, too. I used the case from an old PC 200W power supply. Regards, Janis
